Modeling Polymer Chains

MMD lab graduate Michael Buche just published work started in his PhD thesis in Physical Review E. “Freely jointed chain models with extensible links” presents how to derive asymptotically correct analytical expressions for the force-stretch relationships for polymer chains with extensible bonds utilizing statistical thermodynamics. This work was co-authored with Prof Silberstein and fellow Cornell […]

Paper on modeling ionotronics out in JMPS

The design of functional and soft ionotronic devices has gained a considerable interest over the last decade, with applications ranging from sensing and energy harvesting to drug delivery. The coupled electrochemical and mechanical response of soft ionic polymers plays a pivotal role in the operation of many such devices and presents a significant challenge for […]

Microbial Stress Gordon Research Conference

Prof Silberstein attended and presented a poster with Dr. Joy Zhang’s work at the GRC “Microbial Stress Response: Bacterial Mechanisms for Sensing, Responding and Adapting to Stress” last week.

Atkinson Venture Fund grant awarded for Engineered Living Materials

Prof. Silberstein is part of a winning Atkinson Venture Fund grant team. The interdisciplinary project is led by Prof. Rong Yang in the Chemical and Biological Engineering department at Cornell. This new ELMI project “Engineered Living Materials for Indoor Air Quality Control,” will use a hybrid approach of yeast and synthetic polymers to take on […]

MATERIAL DESIGN BY ADDITIVE MANUFACTURING

Join Cornell University April 29th 10am-4pm for this year’s KK Wang Industry Day on materials design by additive manufacturing – a virtual symposium that merges industry and academia. The program will feature keynote talks, presentations from academic and industrial leaders, and a poster competition. Prof Silberstein will be talking about the MMD lab work on […]

New paper out in Advanced Materials Interfaces

The Research Article “Enabling Tunable Water-Responsive Surface Adaptation of PDMS via Metal-ligand Coordinated Dynamic Networks” is now published in Advanced Materials Interfaces. This work was led by Xinyue(Joy) Zhang. We demonstrated a new design to enable time-dependent adaptation of a polymer via dynamic functionalities. By embedding dynamic metal-ligand coordination into a PDMS matrix, a reversible hydrophobic […]

New papers out on mechanoresponsive elastomer modeling

Dr. Michael Buche’s paper on statistical mechanics derived modeling of mechanoresponsive elastomers is now out in the Journal of the Mechanics and Physics of Solids. Titled “Chain breaking in the statistical mechanical constitutive theory of polymer networks,” it methodically derives a constitutive model for elastomer networks with breakable bonds that encompasses and expands beyond the […]

New publication in Soft Matter Emerging Investigators Issue 2021

Check out our new paper (led by PhD candidate Xinyue(Joy) Zhang! This work aims to isolate the effect of transient metal–ligand crosslinking on the viscoelasticity of polymer networks. A systematic study combining both experimental results and theoretical verification was carried out through a carefully designed system that has no physical entanglements or phase separation. Also, […]

The inextricable links between distribution, behavior, and ensemble . . .

PhD candidate Michael Buche and Prof. Silberstein just published a paper on the constitutive modeling of polymer networks using statistical mechanics in Physical Review E. This work is the first to accomplish a general derivation that starts from arbitrary non-interacting single-chain behaviors and ends in the Cauchy stress. It highlights the naturally-occurring statistical correspondences that […]
